Phylogenetic relationships among Pteridaceae, including Brazilian species, inferred from rbcL sequences
Phylogenetic relationships among Pteridaceae were established using rbcL sequences, parsimony and posterior probabilities. The analyses involved 38 Pteridaceae species native in Brazil (12 of themExpand
Phylogenetic relationships and infrageneric classification of Epidendrum subgenus Amphiglottium (Laeliinae, Orchidaceae)
Epidendrum L. is the largest genus of Orchidaceae in the Neotropical region; it has an impressive morphological diversification, which imposes difficulties in delimitation of both infrageneric andExpand
Five vicarious genera from Gondwana: the Velloziaceae as shown by molecules and morphology
Background and Aims The amount of data collected previously for Velloziaceae neither clarified relationships within the family nor helped determine an appropriate classification, which has led toExpand
Flavonoids of Syngonanthus Ruhl. (Eriocaulaceae): Taxonomic implications
Abstract A list of flavonoids of 22 taxa of Syngonanthus Ruhl. (Eriocaulaceae) is presented. The specimens are distributed chiefly in areas of 'campos rupestres' of the States of Minas Gerais andExpand
Five vicariant genera from Gondwana: the Velloziaceae as shown by molecules and morphology [corrected].
BACKGROUND AND AIMS The amount of data collected previously for Velloziaceae neither clarified relationships within the family nor helped determine an appropriate classification, which has led toExpand
Phylogenetic Inference in Velloziaceae Using Chloroplast TrnL-F Sequences
Abstract The chloroplast trnL-F region was sequenced for 20 species of Velloziaceae sensu stricto plus Acanthochlamys and representative species of Cyclanthus (Cyclanthaceae) and PandanusExpand
Effect of Potato virus X on total phenol and alkaloid contents in Datura stramonium leaves
The present paper reports results of the effect of Potato virus X (PVX) on the contents of total phenols and alkaloids in leaves of Datura stramonium. A significant decrease in the contents ofExpand
Propolis research and the chemistry of plant products.
Covering: 1979 to 2010 Propolis is a honeybee product, composed mainly of wax and resins. The latter have a plant origin and contain substances with biological activity. The composition of propolisExpand
Flavonoids and antioxidant potential of nine Argentinian species of Croton (Euphorbiaceae)
Croton is a large genus of Euphorbiaceae and many of its species are used medicinally. This study was performed to analyze the flavonoid composition and the antioxidant potential of hydroalcoholicExpand
Chemical composition and efficacy of dichloromethane extract of Croton sphaerogynus Baill. (Euphorbiaceae) against the cattle tick Rhipicephalus microplus (Acari: Ixodidae).
The cattle tick Rhipicephalus microplus is widely distributed in tropical and subtropical regions, causing high economic impact on cattle production. The control of tick infestations is regardedExpand
